RESONATOR.

SPECIFICATION forming part of Letters Patent No. 784,082, datedL March 7, 1905.

Application filed May 2,1904. Serial No. 206.057.

Bc it known that I, EDWARD F. SwIe'ERT, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful lmproif'ements in Resonators,of which the following is a specilication.

It is customary in offices where messages of any length are received and transcribed upon typewriting machines or at some distance from the receiver to locate the sounder within a box or casing having an open side and are range said box with the open side facing the.

operator, so as to concentrate and direct the sound-waves in a particular direction and render the message distinct above other sounds without requiring special cli'ort on the part of the operator.

This invention provides a box which preferabl y completely incloses the sounder, a horn being connected to the box and adjustable to admit of throwing' the sound in any direction to suit the location of the operator.

For a full description of the. invention and the merits thereof and also to acquire a knowledge ofthe details of construction of the means for effecting' the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modilication, still the preferred embodiment of the invention is illustrated in the accompanying' drawings, in Which- Figure l is a perspective view of a resonator embodying the invention. Fig. 2 is a detail view of the horn and iittings, showing a portion of the box in section about on the line 2 Q of Fig. l. Fig'. 3 is a longitudinalsection of the litting having' direct connection with the box. Fig. 4 is a detail perspective view of the means for securing the horn at therequired elevation. Fig. 5 is a view similar to 3 of the litting to which the horn is attached.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Thebox forming the housing or casing' in l which the telegraph-souiuler is located is represented at l and is preferably constructed of resonant material, such as wood, possessing the quality of augmenting sound-vibrations. This box or casing' l may be of any size and shape and is mounted upon feet to elevate it from the stand or table, said feet being' preferably of rubber, felt, or leather, so as not to mar the surface of the table or support upon which the box may be placed. Binding-posts 2 are connected to the box and receive the ends of the electric conductor 3, by means of which the current is transmitted to the instrument located within the box and which instrument has the terminals of its helix connected to the binding-posts 9. in any usual way. ',lhe top ol the box is movable to admit ol access being readily had to the interior and is held in place by suitable fastenings Ll..

The means employed for connecting the horn 5 to the box consist of a ring 6 and litting's '7 and 8, the latter being elbows and the several parts connected by screi '-th read joints. The ring' 6 is litted in au opening' in the top of the box and is supported in said opening by an outer flange 9, which is apertured to receive screws or like fastenings for securing the ring in place. The lower end of the elbow-litting 7 is threaded into the ring 0 and its upper end is internally threaded and provided with a boss l0, in which is litted a set-screw ll, the inner end of which bears against a block l2 for clamping the fitting' 8 and holding' it in an adjusted position after the horn 5 has been moved to the required elevation. The clamp block l2 is litted in a recess in the inner side of the threaded portion of the litting T and is provided with a thread 13 to match and register with the thread upon the inner side of said iitting.

The litting S is likewise of elbow form and its inner end is threaded into the upper end of the litting 7 and its outer end has the horn 5 connected thereto. 3y turning the litting 8 in the litting 7 the outer end of the horn 5 may be raised or lowered, so as to throw the sound high or low as may be required according to the position of the operator. After the horn has been moved to the required position the set-screw 1l is tightened to cause the clamp-block 12 to grip the inner end of the fitting 8 and hold it against movement. By turning the fitting 7 in the ring 6 thehorn may be moved to any angular position about a vertical axis.

Having thus described the invention,'\\f'hat is claimed as new isl. In a resonator, the combination of a box, a horn, tubular fittings connecting the horn with the box, and fastening' means for securing the horn when moved to the required point of adjustment, substantially as specified.

2. In a resonator, the combination of a'box, an elbow-litting connected to the box, a companion elbowfitting' connected to the lirst fitting and provided with a horn, and securing means between the two elbow-tittings for positively fastening' then) in the required adjusted position, substantially as described.

3. In a resonator', the combination of a box, a fitting' connected thereto, a second fitting provided with a horn and connected to the first-mentioned fitting' by means of a screwthread joint, a clamp-block applied to one of the fittings, and a set-screw cooperating with the clamp-block to secure the two fittings in an adjusted position, substantially as set forth.

l 4. In a resonator, the combination of a box. l a fitting applied to the box and adapted to be turned about a vertical axis, a second fitting connected to the first-mentioned fitting and movable about a horizontal axis, and a horn connected to said second fitting' and adapted to be raised and lowered at its outer end and to be swung to any angular position about a vertical axis, substantially as set forth.

5. In a resonator, the combination of a box having an opening' in a side thereof, a ring fitted into said opening and having an outer flange overlapping the opening' of the box and receiving fastenings, an elbow-fitting connected to the ring by a screw-thread ljoint, a second elbowfitting threaded to the firstmentioned litting, a horn attached to the outer end of the said second litting, and securing means between the two fittings for holding the horn when adjusted, substantially as set forth.

In testimony whereof I aliix my signature in presence of two witnesses.
